Case Study: The Aroostook County Medical Center

Innovative Heating System Technology Delivers Energy Savings and Cost Efficiency

The Aroostook County Medical Center (TAMC) is the largest hospital in Maine’s northernmost county, serving over 2,000 inpatient and long-term admissions per year* plus more than 30,000 emergency and primary care patients. People in northern Maine depend on TAMC, and the medical center depends on reliable heating and cooling 24 hours a day, seven days a week.

Five years ago, during a time when health care expenses were skyrocketing, the hospital undertook a two-phased, energy saving and fuel conversion project in order to cut costs. The first phase was to replace its aging heating system burners with state-of-the-art Limpsfield burners and Autoflame® burner controls.

The new burners were, in and of themselves, an energy-savings upgrade, but the installation of the Limpsfield brand also allowed the medical center to use multiple types of fuel. Mechanical Services, Inc. was TAMC’s partner for the project.

“Originally, we recommended Limpsfield burners with an Autoflame control system to help TAMC reduce their consumption of #2 fuel oil, and the initial project helped them decrease oil usage by 10%,” reports Mechanical Services president Chris Green. “In the second phase we worked with them to convert their systems to compressed natural gas (CNG), which was less expensive than #2 oil at the time.” See TAMC’s full Energy Savings Report.

“Because Limpsfield systems can fire up to four different fuel types at the flick of a switch,” adds Chris Green, “TAMC can use their new system to burn the most cost efficient fuels at any time.”

Aroostook County Medical Center was the first facility in the state – and only the second in the country – to convert to compressed natural gas for heating and cooling. Sylvia Getman, president and CEO of the hospital, said, “The switch [to compressed natural gas] promised to reduce TAMC’s fuel costs significantly.” The conversion also had a positive impact on the environment. Getman continues, “This not only makes sound economic sense and helps us advance our mission, but allows us to greatly reduce our carbon footprint and makes our organization a much better steward of the environment.”

With annual savings projected between $400,000 and $500,000, the hospital’s return on investment was expected in less than one year.

Case Study: Concord Hospital Upgrades Heating System

Hospital Achieves 8-12% Annual Efficiency Savings and Lowers Carbon Emissions

Concord-Hospital-ccdConcord Hospital is a 295-bed acute-care facility that, like most hospitals, never closes. When it comes to treating sick or injured people there’s no time for down time. So as the hospital’s heating system began reaching capacity during cold winter days when heating demand was at its peak, Concord’s facilities management team knew it had to explore new systems options to keep its 24/7 operations running efficiently.

After a comprehensive infrastructure and energy consumption assessment the hospital decided to build a larger, more comprehensive facility in order to meet their growing needs both now and into the future.

Boiler Plant Manager, Gary Powell, recalls, “We hired the engineering firm Fitzemeyer and Tocci, and began the selection of equipment and design of the new building.” Equipment recommendations included three new Superior Boilers using Limpsfield burners and Autoflame® burner controls.

Mechanical Services: Limpsfield and Autoflame Experts

As New England’s exclusive distributor of Limpsfield burners and Maine’s only certified installer of Autoflame control systems, Mechanical Services, Inc. was selected for the implementation of Concord Hospital’s new heating system.

“Concord Hospital was looking to build a new state-of-the-art boiler plant, and they chose Mechanical Services because of our experience with leading-edge technology like Limpsfield and Autoflame,” stated Mechanical Services president, Chris Green. “The technology will not only meet the hospitals’ growing energy needs, it will also help them improve energy efficiency and reduce greenhouse gases.”

“The new boilers were fitted with Limpsfield low NOx burners, which provide maximum efficiency with negligible CO emissions,” confirms Gary Powell. “And the Autoflame burner controls allow us to achieve significant fuel and emissions savings versus conventional systems.” The new system is expected to result in annual fuel savings of 8 –12%.

Mechanical Services Helps Hyde School Score A+ on Natural Gas Conversion

The historic Hyde Mansion sits atop a gentle sloping hill on The Hyde School campus in Bath, striking a Maine parallel to the current PBS hit series, Downton Abbey.

Bath, Maine (April 11, 2013) — The historic Hyde Mansion sits atop a gentle sloping hill on The Hyde School campus in Bath, striking a Maine parallel to the current PBS hit series, Downton Abbey. While education is their main focus, school officials are pleased with the recent conversion from oil to natural gas. Their investment has a one-year pay back, scoring an A+ for energy savings and sound business planning.

“The transition from oil to gas was seamless,” remarks Hyde School Executive Business Manager Cindy Morgan. Hyde School worked with Mechanical Services, a statewide HVAC company starting in September of 2012 after the pipeline was installed last summer.

Fourteen buildings on campus are now heated with natural gas from the Hyde Mansion to the newly constructed residence hall. “Each building presented a different set of issues and Mechanical Services worked with us to create unique solutions,” says George Paton, Hyde School facilities manager.

New technology installed by Mechanical Services will help the Bath, Maine school save energy and money.

“The Hyde School conversion to natural gas is a perfect example of how new technology is helping save energy and money in ways unimaginable when the facility was built a century ago,” says Mechanical Services President Chris Green. “The original heat source was coal and our team thrived on creating solutions to meet each job’s specifications.”

Underneath the mansion’s gracefully-appointed rooms, oil-fired steam boilers are equipped with state of the art Webster natural gas burners with an Autoflame Combustion Management system. In addition, Mechanical Services installed a code compliant stainless steel lining system in the 100-year old chimney.
